Hi Pete,
Thanks for your post, just to clear up a few misconceptions about Visigo.
Visigo and UTM/SWG are very much separate products, however if you are an SW customer you do have support for free which effectively gives you a discount.
Although they work well together, having them separately allows us to reach out to schools not using our filtering as it works well with other systems.
Visigo is very much a service and not a software.
The Visigo threat library is very advanced and has 55 languages and common spelling mistakes/slang/romanised scripts as well profiling features and clever software that is able to see the words in context. We also have an expert team who put alerts through to the school in real time.
I hope this clears things up
